old fashioned dark-panelled sitting-room, a dining-room, bedroom and dressing-room, and, save for the fact that I was compelled to be on duty after four o'clock, when Sir Bernard drove to Victoria Station, my time in the evening was very much my own. Many a man would, I suppose, have envied me. It is not every day that a first-class physician requires an assistant, and certainly no man could have been more generous and kindly disposed than Sir Bernard himself, even though his character was something of the miser. Yet all of us find some petty shortcomings in the good things of this world, and I was no exception. Sometimes I grumbled, but generally, be it said, without much cause. Truth to tell, a mysterious feeling of insecurity had been gradually creeping upon me through several months; indeed ever since I had returned from a holiday in Scotland in the spring. I could not define it, not really knowing what had excited the curious apprehensions within me. Nevertheless, I had that night told my secret to Ambler Jevons, who was often my visitor of an evening, and over our whiskies had asked his advice, with the unsatisfactory result which I have already written down. CHAPTER II. "A VERY UGLY SECRET." The consulting-room in Harley Street, where Sir Bernard Eyton saw his patients and gathered in his guineas for his ill-scribbled prescriptions, differed little from a hundred others in the same severe and depressing thoroughfare. It was a very sombre apartment. The walls were painted dark green and hung with two or three old portraits in oils; the furniture was of a style long past, heavy and covered in brown morocco, and the big writing-table, behind which the great doctor would sit blinking at his patient through the circular gold-rimmed glasses, that gave him a somewhat Teutonic appearance, was noted for its prim neatness and orderly array. On the one side was an adjustable couch; on the other a bookcase with glass doors containing a number of instruments which were, however, not visible because of curtains of green silk behind the glass. Into that room, on three days a week, Ford, the severely respectable footman, ushered in patients one after the other, many of them Society women suffering from what is known in these degenerate days as "nerves." Indeed, Eyton was _par excellence_ a ladies' doctor, for so many of the gentler sex get burnt up in the mad rush of a London season.
